Abstract

A unique treatment for pigments is provided. This treatment, which uses certain organo-phosphoric acids and/or their salts, imparts improved physical and chemical qualities including lacing resistance, improved dispersion and decreased chemical reactivity when these treated pigments are incorporated into polymeric matrices.

Claims (26)

1. A pigment comprising a pigmentary base that has been treated with the products resulting from the reaction of organic alcohols and either P2O5 or phosphoric acid, wherein said products are present in an amount from about 0.01 percent to about 5 percent by weight based on the weight of the pigmentary base.
2. A pigment according to claim 1, wherein the pigmentary base has been treated with the products resulting from the reaction of organic alcohols, and phosphoric acid.
3. A pigment comprising a pigmentary base that has been treated with an organo-acid phosphate compound having the formula:
(R-O)x PO(OH)y wherein x = 1 or 2;
y = 3-x; and R is an organic group having from 2 to 22 carbon atoms, and wherein the organo-acid phosphate compound is present in an amount from about 0.01 percent to about 5 percent by weight, based on the weight of the pigmentary base.
4. A pigment according to claim 1, wherein the pigmentary base is selected from the group consisting of titanium dioxide, kaolin, talc, mica and calcium carbonate.
5. A pigment according to claim 3, wherein the pigmentary base is selected from the group consisting of titanium dioxide, kaolin, talc, mica and calcium carbonate.
6. A pigment according to claim 4, wherein the pigmentary base is titanium dioxide.
7. A pigment according to claim 5, wherein the pigmentary base is titanium dioxide.
8. A pigment according to claim 1, wherein the pigmentary base is treated with a compound selected from the group consisting of polyalcohols, alkanolamines, aluminum oxide, silicon dioxide and zirconium oxide.
9. A pigment according to claim 3, wherein the pigmentary base is treated with a compound selected from the group consisting of polyalcohols, alkanolamines, aluminum oxide, silicon dioxide and zirconium oxide.
10. A pigment according to claim 8, wherein the pigmentary base is treated with trimethylolpropane or triethanolamine.
11. A pigment according to claim 9, wherein the pigmentary base is treated with trimethylolpropane or triethanolamine.
12. A pigment according to claim 1, wherein the organic alcohol is a hexanol or an octanol.
13. A pigment according to claim 3, wherein R is hexyl- or octyl-.
14. A pigment according to claim 1, wherein the organic alcohol is 2-ethylhexanol.
15. A pigment according to claim 3, wherein R is 2-ethylhexyl-.
16. A pigment comprising a pigmentary base that has been treated with a salt of the organo-acid phosphate compound as defined in claim 3.
17. A polymer matrix comprised of a polymer and the pigment of claim 1.
18. A polymer matrix comprised of a polymer and the pigment of claim 3.
19. A polymer matrix according to claim 17, wherein the polymer is polyethylene.
20. A polymer matrix according to claim 18, wherein the polymer is polyethylene.
21. A polymer matrix according to claim 17, wherein the amount of the pigment is from about 50 percent to about 85 percent by weight of the polymer matrix, based on the weight of the polymer matrix.
22. A polymer matrix according to claim 18, wherein the amount of the pigment is from about 50 percent to about 85 percent by weight of the polymer matrix, based on the weight of the polymer matrix.
23. A method for preparing a pigment, comprising combining a pigmentary base and an organo-acid phosphate compound, wherein the organo-acid phosphate compound comprises of the reaction products of organic alcohols, and either P2O5 or phosphoric acid.
24. A method for preparing a pigment, comprising combining a pigmentary base and an organo-acid phosphate compound, wherein the organo-acid phosphate compound has the formula:
(R-O)x PO(OH)y wherein x = 1 or 2;
y = 3 - x; and R is an organic group having from 2 to 22 carbon atoms; and wherein the amount of organo-acid phosphate is from about 0.01 to about 5 weight percent based on the weight of the pigmentary base.
25. A method according to claim 24, wherein said combining occurs at a temperature of from about 10°C to about 270°C.
26. A method for treating a pigment comprising treating a pigmentary base with a salt of the organo-acid phosphate compound as defined in claim 24.
